MailServe For Monterey with DKIM Support

Category : Technology/MailServeForMontereyWithDKIM.txt

I've released a MailServe for Monterey with support for DKIM

This is one of the hardest thing I've done. To build OpenDKIM for Mac OS, I have to build libmilter, which depends on Unbound, which depends on Expat And I have to build Automake and Autoconf before that. At each step of the way, build failures abound. No wonder, I realised, I gave up so many times before.

But here it is, a rare sighting of opendkim and libmilter for Mac OS in the wild, in Intel and ARM versions.

You can paste in your DKIM keys from a current implementation Or simply generate a new key pair afresh. Either way, it only takes three steps to have a DKIM-enabled mail server 1. Generate DKIM Keys 2. Enable DKIM 3. Restart Mail Server. That's it.

Enjoy! Better late than never? :) Happy New Year...

OpenVPN Enabler For Mac OS Monterey

Category : Technology/OpenVPNEnablerForMOnterey3dot1dot1.txt

I've released version 3.1.1 of OpenVPN Enabler for Monterey.

This fixes a bug with the launchd plist for the auto-scan job (for incoming threats to the mail server) that caused the job not to run.

The Mail Threats table now separates new threats from threats that have already been blocked.There is now a time stamp shown for the last scan done on the mail server log, and the new threats are listed after that line. Also the table display always scrolls down to display the latest threats, if any.

You can download it now. For free :). Enjoy!

OpenVPN Enabler For Mac

Category : Technology/OpenVPNEnablerForMac.txt

Version 3.1 of the OpenVPN server installer for Mac, OpenVPN Enabler for Monterey, now features a user interface for the Mac OS Packet Filter (PF) Firewall.

You can enter a table of IP addresses you want to keep out. And it automatically builds a table of mail-server-related threats by scanning the Postfix log at /var/log. You can set the scan job to run every few hours, so new threats are automatically swept up and nullified.

OpenVPN Enabler for Monterey is free and available for download now.

OpenVPN Enabler For Monterey

Category : Technology/OpenVPNEnablerForMonterey.txt

I've released OpenVPN Enabler For Monterey. It's free for download at http://cutedgesystems.com/software/OpenVPNEnablerForMonterey

Now that I've been able to explore it again in depth, OpenVPN is surprisingly powerful. It does everything that the old Apple built-in VPNd can do. And it has the potential to do even more — if I can get more time to work on it.

OpenVPN is very stable. Client profiles on the Mac and iOS devices are easy to set up.

And, once you're connected to the VPN, all traffic to servers that you talk to, through the VPN, look like they're coming from the local network. And you can reach any resource on the local network using its local IP address, and this includes printers and other Macs (via Screen Sharing, File Sharing and Remote Login). Just like as if you're physically on the local network.

Just about the only thing you can't do is browse the local network through a visual interface, like the Finder. For that, we'll need to go a few steps further and explore the use of the TAP interface. Now we're just using TUN. But maybe it's just as well not to expose too much of the local private network.

OpenVPN Enabler For Monterey 3.0 is ready for download now.

MailServe and WebMon MacOS Monterey

Category : Technology/MontereyApps2.txt

Finally, I've released MailServe for Monterey and WebMon for Monterey.

I almost gave up when I couldn't get Dovecot to work on Monterey for the longest time.

Now I can say, at least I've gotten back all the steps that I've lost when Apple started breaking things in Monterey. Now, I can move forward, at last, and do new things.

Letsencrypt Enabler for Monterey

Category : Technology/MontereyAppsLetsencrypt.txt

Letsencrypt Enabler for Monterey is available here.

This is the base, on top of which I can try to get the web server and mail server working again for Monterey.

I'll work on the mail server next, now that I know how to get Dovecot working on Monterey again. As for the web server, the loss of PHP from a stock MacOS installation is a pain.

MacOS Monterey "Enablers"

Category : Technology/MontereyApps.txt

I've released my first Monterey apps. DNS Enabler and DNS Agent for Monterey are both out. They can be found here (DNS Enabler) and here (DNS Agent).

I've figured out how to make Dovecot run again on Monterey. A version of MailServe for Monterey will be out by the end of this week, together with a version of Letsencrypt Enabler for Monterey.

As for WebMon, I have yet to figure out how to build PHP from source for Monterey, which does not come with a built-in PHP. AS usual, I would like to figure out how to build all these without Homebrew, if I can, which is an order of magnitude harder, but you'll learn more as you do it on your own.

MacOS Monterey

Category : Technology/Monterey.txt

If you're wondering if I have a version of MailServe ready for Monterey, I have news for you — I can't (yet) make Dovecot work with Monterey.

I think it's something Apple changed, related to setting entitlements for executables that need to do authentication or access system-level files.

Anyway, I don't have much information to find a fix at the moment. Dovecot just doesn't work on Monterey.

I barely got BIND/named working again on Monterey.

I hate this ritual every year, fixing things that worked but are now breaking all over the place. Last I heard, Monterey doesn't have PHP.

If we could have a stable OS to build on, we could make the Mac the best Unix platform ever. As it is, I wonder what Apple is thinking when it tries to make the Mac as closed as iOS. What if they released an OS and all the Unix people stayed away?

MacOS Catalina

Category : Technology/macOSCat.txt

I'm still working on new Catalina versions of all my apps. I have some problems still with the new method of getting admin rights, using launchd.

If you're interested to test a Catalina version of any of my apps, write me via email.

The one app that I still can't get to work on Catalina is VPN Enabler. No more PPTP, and L2TP over IPSec seems to have some unfathomable problem. So, I'm not sure if I can even get that to work.

More news over the weekend.
